ALTERNATIVE METHODS FOR ANTIREFLECTION OF OPTICAL SURFACES WITH USE OF THE TRANSITION LAYERS AND DIFFRACTION GRATINGS

摘要

The new methods for antireflection of optical surfaces with use of the transition layers and diffraction gratings, is researched. The optimal profile of refractive index variation for transition layer is determined. For antireflection of the boundary "transparent dielectric - air" the relief diffraction grating is shaped on surface of dielectric. The profiles of grating groove that minimize of reflectance, is searched.
